PIER OR FERRY RACK.

` SPEIFICATION forming part of Letters Patenta No. 288,308,-dated November 13, 1883.

i Application filed April 30, 1383. mdmoqe l To all whom; it may concer Be it known that I, HENRY CASE, a citizen of the United States of North America, and

aresident of Brooklyn, County of Kings, State of New York. have invented a new and useful Improvement in Pier or Berry Hacks, of which the following is a specification.

The object of this invention is to provide an improved device for protecting pies, breakwaters, and like structures from collision of steamboats and other vessels, and from heavy seas, and at the same time to a'fford protection from injury to steamboats or other vessels coming to or lying at piers, breakwaters, ferryslips, and the like, while affording, also, every convenience for the landing of passengers or freight.

The invention consists of an improved form of trussed pier or ferry rack constructed ofpiles and timbers, combined and arranged in a novel manner, as hereinater i'ully set forth.

Reference is to be had to the accompanying drawiugs, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures. y

Figure l is a plan of my improved device as applied to a pier, wherein the gang-plank is indicated in dotted lines. Fig. 2 is a sectional side elevation online :r m, Fig. =1. Fig. 3 is an enlarged plan of a detailed portion of the structure. Fig. 4: is an enlarged partlysectional. side elevation of a detailed portion of the structure. Fig. 5 represents a front elevation of a portion of the structure, with parts broken away to exhibit other parts.

In the drawings, A represents apier, of which A' represents the lower or landing platform, and A" the top or upper platform, which is designed to be reached from the said lower platform by stairs or steps. (Not shown.)

My improved rac-k B is designed to be fixed at asuitable distance-say eight feet, more or lessfrom the pier,breakwater, or other structure it is designed to protect, and consists of piles C, driven in two parallel rows, D D', about two feet apart, more or less, the piles of the outer row, D, having their tops two or three feet (more or less) higher above water than the piles of the inner row, D', so that they are at such au elevation that the guards of. a.

boat coming` or lying alongside' cannot become caught on them. Between these rows of piles stout timbers, or stringers E E are secured horizontally by bolts a, passing through both piles and timbers, as shown, whereby this part of the structure is stiffened and strengthened.

Preferably, no out'er piles, D, are driven at or opposite the end of the gan g-plank F, this space F' being left clear to the easy loading or unloading of passengers or freight, and the tops of the piles D', that are opposite this space F',

cut off' level with the upper surface of the stringers E E, as indicated in Fig. 5, so that the outer end of the gang-plank F may eXtend over them and be secured on the said string ers E E, preventing inj ury to the guards of a vessel. The gang-plank F has its outer end secured by bolts b upon the upper faces of the stringers E E, as shown, while its inner end, to which is hinged a Shoe, c, extending inward,

rests on a roller or wheel, d, on the landingr platform A' of the pier A, the said roller d permitting the free inward and outward motion of the plank F when the raclr B is swayed by contact of boat or vessel, or motion of the waves. So far as described, this portion of the rack may not (lili-er, essentially, from others in use, and would be well adapted for rivers and harbors where smooth water prevails, which are not subject to heavy seas. i

To ada-pt the racl; :for breakwaters, piers, and the like, which are eXposed to heavy seas and severe storms, I construct it with one or more inside braces or horizontal trusses, G, each of which consists of a double row, H, of piles f, a timber, I, Secured to a stringer E by bolt or bolts g, and extending between the rows' of piles H, with its inner end reaching beneath the pier-top. Diagonally-placed timbers K K, having their outer ends secured to the stringer E and their inner ends to the timber I, add strength to the brace or truss, and bolts h h, holding the timber I and piles f f ri gidlytogether, complete the truss or brace G. lt

endure for any conside'rable time.

conditions, afford no adequate protection, nor

For ferryslips the improved rack, while being more durable than those now in general use, will be found to possess all the' elasticity that may be desired.

Having thus described my invention. I claim as new and desireto secure by Letters Patent- 1. An improved pier or ferry rack, constructed substantially as herein shown and described, consisting of 'parallel rows D D' of pi1es, stringers'E E, and horizontal braces or trusses G, all combined and arranged' as set forth. i

2. In a pier or ferry rack, the combination, with rack B, constructed of pile-rows D D' and stringers E E, secured thereto, of braces- G, secured at right angles thereto on the inside toward the pier, and consisting of plerows H H and tmbers I K, combined and arranged substantially as heroin shown and described. i i

3. In a pier or ferry rack, the combination of rack B, having space F' devoid of ples, attached gang-p1ank F, and braces or trusses G, substantially as herein shown and described. In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 26th day of April,

HENRY CASE.
